I'm in CA so my prices maybe different than yours. It was $120 but concidering it's only the second servicing in 17 years I think it was well worth the money.
The price to me sounds very reasonable. This is a work horse of a machine. With the correct needles you can sew denim easily and even do copper punching. If you don't get a user manuel let me know and I'll photocopy mine and mail it to you.
